Definitions

  • the invention relates to a connecting element for fixing and holding components of a secondary structure, such as traverses, leveling floor panels and the like, on a rail profile provided with a hole division, in particular on seat rail profiles in commercial aircraft, by means of lockable mushroom-shaped studs which interact with the seat rail profiles.
  • the object of the invention is to provide an element for this area of application, with which components of a secondary structure, such as parts of a leveling floor system, cross struts or the like, can be fixed and held in a simple manner on the rail profiles forming the primary structure.
  • a secondary structure such as parts of a leveling floor system, cross struts or the like
  • connection element shown in Fig. 1 consists essentially of a support body 1, which has an approximately cylindrical shape and on which four connection flanges 2 to 5 are formed in one piece, offset from one another by 90 degrees.
  • a base plate 6 is also integrally formed on this structure forming a node, the support body 1 and the connecting flanges 2 to 5 being arranged approximately perpendicular to the base plate 6.
  • Carrier body 1, connecting flanges 2 to 5 and base plate 6 are made in the case of the embodiment described here as a common casting; it is of course also possible within the scope of the invention to design it as a forged or milled part.
  • the carrier body 1 has a bore 7 running in the axial direction, which tapers with a shoulder 8 after about a third of the longitudinal extent of the carrier body 1 and which also extends through the base plate 6.
  • a screw 9 is arranged and held by a nut 10, which rests on the paragraph 8.
  • the screw bolt 9 carries at its lower end facing the base plate 6 a mushroom-shaped member firmly connected to it Attachment 11, which is flattened on two sides.
  • the screw bolt 9 and thus also the shoulder 11 can be rotated via a slot provided at the upper end of the screw bolt 9.
  • lugs 12 and 13 On the underside of the base plate 6, two approximately cylindrical lugs 12 and 13 are attached, the diameter and spacing of which correspond to the hole pitch of the seat rail profile shown in FIG. 4.
  • the lugs 12 and 13 have recesses 14 and 15, respectively, which correspond to the swivel radius of the mushroom-shaped attachment 11 and which, as can be seen in FIGS. 3b and 3c, limit the rotational movement thereof as stops.
  • the arrangement is completed, as can be seen in Fig. 3a, by a transport lock 16, which is provided with two pins 17 and 18 which engage in corresponding bores 19 and 20 of the lugs 12 and 13.
  • connection element The installation position of the connection element described above is shown in Figures 4 to 6.
  • the screw bolt 9 is first rotated so that the mushroom-shaped attachment 11 is in its unlocked position, in which the flattened sides are parallel to the long side of the base plate 6 and thus at the same time on the recesses 14 and 15 of the lugs 12 and 13 formed stops abut, as shown in Fig. 3b.
  • connection element can be inserted into a seat rail profile 22 embedded in a floor plate 21 such that the two lugs 12 and 13 each engage in two adjacent hole-like extensions of the seat rail profile 22.
  • the seat rail profile 22 forms the primary structure on which by means of a number of similar connection elements a secondary structure, which in the case of the exemplary embodiment shown here consists of cross struts 23 and 24, additional seat rails 25 and a second layer of floor panels 26, is to be fixed and held.
  • the mushroom-shaped attachment 11 is pivoted under the seat rail profile 22 and brought into contact with the latter without play by tightening the nut 10.
  • the path of the top 11 is again limited by the two approaches 12 and 13, as can be seen from Fig. 3c.
  • the node formed by the connection element described here is thus locked and the components 23 to 26 of the secondary structure can be attached to the flanges 2 to 5.
  • a bore 27 in the seat rail profile 25 ensures that the screw bolt 9 remains accessible, so that it is also possible to fasten the connecting element to the primary structure together with the components of the secondary structure already mounted on it.
  • connection element can be used by simply shortening it to different installation heights, so that it can also be attached to connection points of the primary structure which have different heights or can also be used with inclined floor systems.
